iNlPROVED EVAPORATING-PAN FOR SUGAR-AND SIRUP.

Specification forming part of Letters Patent No. 43,220, dated June 2l, ISGJ.

T0 all' whom, it may concern? Be it known that- I, Lnwrs MEeoWnN, of Upper Alton, in the county of Madison and State of Illinois, have invented a new and Improved EvaporatingPan 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a plan top view of my invention. Fig. 2 is a transverse vertical section ofthe same. Fig. 3 is a longitudinal vertical section of the same.

Similar letters of reference in the three views indicate corresponding parts. A

This invention consists in the application to an evaporating-pan of oscillating skimmers hung on gudgeons, which have their bearings in lugs orv standards rising from the ends of the pan, and are provided with slots to clear the partitions of said pan, in combination with its curved sides, and with troughs running along their edgesin such a manner that `by the action of said skimmcrs the scum rising in the several compartments of the pan can be thrown out into the troughs with little exertion or loss of time.

The invention consists, also, in a pan provided with a series of transverse partitions with holes near the bottom, arranged in a zigzag line, in combination with a well at the inner end communicating, through suitable gates, with two finishing-pans placed over separate iiues, either one of which can be opened and closed independently of the other, and with suitable skimmers, in such a manner that the juice in passing through the First pan is heated, and when freed from its impurities passes into the well, and thence in the finishing-pan, where it is readily boiled down to the required consistency.

A represents a pan, made of sheet metal or any other suitable material, and placed on an arch, B, which may be built up of brick, or made of any other suitable material, and which is to be provided with a lire-grate on one end, so that a fire can be made and the pan can be heated in the ordinary manner. rIhe sides a of the pan A are curved, and they describe a portion of a circle the centers of which coincide with the centers of the gudgeons Z, from which the skimmers C are suspended. These skimmers consist of flat metal plates, with lips turned inward at their lower edges, and slotted to clear the partitions c in the pan. The gudgeons b have their bearings in lugs or brackets d, rising from the ends ot' the pan, and said gud geons extend through. the brackets at the outer ends to form cranks by means ot' which the skimmer-s can be operated, and at the inner ends to make room for disks c, provided with oneI or more teeth, which can be made to engage with pawls f, attached to the edges of the pan, so that by throwing said pawls in gear with the disks the skimmers can be held'up in any desired position. Said skimmers extend down into the pan to such a depth as may be requisite to enable them to reach the scum that'rises on the surface of the juice, and by turning them out towardthe edges of the pan the scum is sweptoff into troughs D, which are rigidly attached to the sides ofthe pan A. The partitions c divide the pan into a number of compartments, which communicate with each other by means ofholes c', which are made in the partitions close down to the bottom of the pan, and which are arranged in a zigzag line, so th at the juice has to travel transversely across each partition in or der to pass from one end of the pan to the other. During this zigzag course the juice alternately passes over the hottest portion ofthe pan, causing the scum to rise and to iloat off toward the sides, `whence it can be easily removed by the skimmers. Aportion ofthe last compartment of the pan A forms a well, g, extending across the whole width of said pan, and this well communicates, by means of openings lt and gates h', with the iinishingpans E. IThese finishing-pans are situated over the two ilues F, which extend from the arch B to the chimney G. Each of these uescan be opened or closed by means ot' dampers 13, so that either one of said pans can be cooled without interrupting the operation of boiling the juice in the other. By these means one batch of juice after the other can be tinished without interruption, and a good sirup is produced with comparatively little labor and expense in fuel.

Vhat I claim as new, and desire to secure by Letters Patent, isv l. The oscillating skimmer G, slotted to lit the partitions c of the pau A, and suspended holes c', uishng-pans E, double lues F, and from gudgeons b, in combination With the dempers z', all constructed and operating in spherical sides a 0f the pan, and with the the manner and for the purpose speeed.

troughs D constructed and operating in the manner aud for the purpose substantially as LEWIS MEGOWEN herein shown and described. vWitnesses:

2. The well g, in the last compartment of JOSEPH BURNAP, the pan A, in combination with the zigzag W. CAMPBELL.
